Shares of Amazon plummeted in extended trading, after the company posted a big earnings miss for the holiday quarter. The Internet retail giant reported Thursday fourth-quarter net income of $1 per share on $35.75 billion in sales, missing the $1.56 per share on $35.93 billion in revenue expected by a consensus estimate from Thomson Reuters.

Still, there was a bright spot in the report: Amazon Web Services, which dominates the cloud-computing industry saw its sales rise to $2.41 billion in the quarter, up 69 percent from the previous year and beating estimates.

Fellow cloud-technology giant Microsoft also reported earnings Thursday afternoon, and shares were boosted after earnings and revenue beat analysts' expectations. The company posted fiscal second-quarter, adjusted earnings per share of 78 cents on $25.69 billion in revenue. Analysts had expected Microsoft to report earnings of about 71 cents per share on $25.26 billion in revenue for its fiscal second quarter, according to a consensus estimate from Thomson Reuters.

Shares of gamemaker Electronic Arts fell after the bell, despite posting a 26.3 percent revenue increase during the holiday quarter, according to Reuters. EA raised its full-year profit and sales forecasts slightly, predicting strong sales of "Star Wars: Battlefront," a first-person shooter game that has already surpassed 13 million units sold, Reuters reported. Another game maker, Activision Blizzard, also sank in extended trading. The company makes games like "Call of Duty" and "StarCraft."

Norwegian Cruise Line Holdings stock spiked in extended trading after falling during the regular trading session. In response to an outbreak of mosquito-borne Zika virus, Norwegian and rival Carnival said they would allow expectant mothers covered by the CDC advisories to reschedule cruises to a later date or switch to an itinerary outside the affected countries, Reuters reported.
